With Fang Fa He Fitness the The Fang Fa Tight firmware of the hole Inner on Yu Will Group Woven or phase Should Jia Body Jian Tight Gu Dao Let what people's bone or Move object bone
The present invention relates to will for example be suitable for that the graft (1) of tendon or ligament or prosthese part is replaced to be fastened on the method in bone hole road or blind hole by fastener (3). In the first step, by by fastener (3) be pressed into bone hole in or by by fastener be located in bone hole and with Hou expand bone hole and by graft (1) or prosthese part press-in cooperation in duct or bone hole, which contacts with graft (1) or prosthese part and contacts with the bone wall of duct or blind hole. In the second step, by the liquefiable material being liquefied near the bone wall being in contact with fastener, by being anchored at liquefied infiltration by fastener (3) in wall in the bone wall of duct or blind hole to the marrow. To what second step, the anchoring piece (6) comprising liquefiable material is advanced with respect to what fastener (3), and the preferred vibrational energy of energy is transported simultaneously to anchoring piece (6) or fastener (3). The fastener surface of setting what anchoring includes the oral area or groove of access, and fastener surface is connected to by the access with fastener inner cavity (4), and the groove self-tightening firmware proximal end face extends to fastener distal end.本發明涉及借助緊固件(3)將例如適用於取代肌腱或韌帶的移植物(1)或假體件緊固在骨孔道或盲孔內的方法。在第一步驟中，通過將緊固件(3)壓入骨孔內或通過將緊固件定位在骨孔內並隨後擴張骨孔而將移植物(1)或假體件壓入配合在孔道或骨孔內，該緊固件(3)與移植物(1)或假體件接觸並與孔道或盲孔的骨壁接觸。在第二步驟中，借助在與緊固件相接觸的骨壁附近被液化的可液化材料，通過使已液化的材料滲透入骨壁內將緊固件(3)錨固在孔道或盲孔的骨壁內。對於第二步驟，包含可液化材料的錨固件(6)相對於緊固件(3)被前移，並且能量優選振動能被同時傳送至錨固件(6)或緊固件(3)。設置用於錨固的緊固件表面包括通路的口部或凹槽，所述通路將緊固件表面與緊固件內腔(4)連通，所述凹槽自緊固件近端面延伸向緊固件遠端。
